创建webservice服务

@WebService(name="prizesWebservice")
public class PrizesWebservice {

    /**
     * 获取目标辨认列表
     * 供系统实现目标列表对外对接，同步接口，立即返回
     * @return
     */
    public String getPrizesAll(){
        return StringUs.PRIZES;  //模拟接口返回XML格式数据
    }
    
    /**
     * 通过输入主键编号，返回视频的http地址
     * 供系统实现返回视频地址对外对接，同步接口，立即返回
     * @param id 主键编号
     * @return
     */
    public String getPrizesFile(String id){
    	return StringUs.PRIZESFile; //模拟接口返回XML格式数据
    }

    //通过EndPoint(端点服务)发布一个WebService
    public static void main(String[] args) {
     /*参数:1,本地的服务地址;
           2,提供服务的类;
      */
     Endpoint.publish("http://192.168.1.110/vicpln/services/prizesWebservice", new PrizesWebservice());
     System.out.println("发布成功!");
    }
}

浏览器访问http://192.168.1.110/vicpln/services/prizesWebservice?wsdl得到如上说明服务正确发布。

使用SOAP获取服务

	 */

测试类

public class Test {

		FileServer fs = new FileServer();
		//没有参数
		String rt = fs.getFile("getPrizesAll",null);
		System.out.println(rt);
		//有参数
		rt = fs.getFile("getPrizesFile","123");
		System.out.println(rt);
